How i can customize objectMapper of swagger?

Question

I have spring boot application with openapi. My openapi was generated by swagger.

Problem:

When i add additional field to response which my service have to parse, i get error

com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "myField”

Because openapi of my service doesn’t know about this field.

And solution for it :

1. Just add annotation to generated classes

@JsonIgnoreProperties(ignoreUnknown = true)

or

1. add this code snippet

objectMapper.configure(DeserializationConfig.Feature.FAIL_ON_UNKNOWN_PROPERTIES, false);

How i can do it in swagger?

1. How i can customize code generation that swagger generates classes with this annotation?

@JsonIgnoreProperties(ignoreUnknown = true)

1. How i can customize objectMapper of swagger therefore swagger used with objectMapper tuned with this option DeserializationConfig.Feature.FAIL_ON_UNKNOWN_PROPERTIES, false);
